The flow spout is provided with the usual well 3,andarrange'd at the bottom of the well is the usual removable variablesize bushing 4, the well and bushing constituting the flow orifice; andlplug 7, for itis well known in the glass 4art .4 mold gobs`,which arethen severed, and. drop into The purpose of the provide new and improvedmeans for conf'trolling theoperation. of .the reciprocable Referring tothe drawings more in detail.,

The cylinder 8 is shown as mounted on a andthe cross armis locked to the iston rod 4,

by lmeansof nuts 12 12. By re erence to Figure 4, it will be observedthat the opening 13 is elongated or slotted. v It is evident that bymeans of this elongated openin the cross arm may be moved forwardly orackward in ahorizontal plane, to bring the plug 7 carried thereby, inproper alignment with the flow orifice. `It will be understood 'that the.adjustment just described is provided sol that the feeder is suited tovarious installations; and the finer adjustments for accuratelymaintaining the plug aligned withv the flow orifice, for overcoming dermations in the plug, etc., will be described below.

The specific means illustrated herein for holding the feeder plug 7,consists of a rig1d larm 14 to which is pivotally attached at 15 theSwingin arm y16; the two arms being ro-l vided at their free ends withfingers 17 w ich are adaptedto embrace the upper endfof the plu '7, asclearly illustrated in the drawmgs.

e upper end of the plug 7 is pierced y through the plug, an this passa eis adapted to receive a. pin 18; one end o the pin being screwed intothe fixed finger '17, as 1nd1- I -4 l, p .catedby numeral 19, andtheother endA of the present invention is to f movable finger 17, theopening 2O being somepin is loosely received 'in anppening 20 in theextending entirelyv what larger'thanthe pm; so that the arm `24, therebmay be moved back and'uforth pon its pivotl -the pin 18. A newiplug isthen mounted on the pin 18, the arm 16 is moved to close'dy position,and the parts are wedged into plug grippin position by lowering the dog21.

It wil be understood that the specific mechanism for securing theplug isto be considered in an illustrative rather than a limiting sense, forthe invention contemplates the use of any suitable means for securingthe plug.

A rounded .rod 23 is formed integral with and extends from the arm 14,and this rod 23 is fitted into a socket 24`provided in theend of thecross,arm' 11. The end ofthe cross arm adjacent the socket is split, asindicated by numeral 25` in Figure 1, anda screw 26 is provided forclamping `the socket aboutV the rod 23, for securely maintaining thelatter in adjusted position. `The construction just described providestwo adjustments for the feed plug 7, as indicated below.

It is apparent that by loosening-the screw 26'the rod 23 carrying thefeeder plug 7, may-beadjusted longitudinally in the socket accuratelypositioning the plug in vertica l alignment with the How' orifice; andby setting' `up on the screw 26the plug will be maintained in itsaligned position.

It will also be apparent that by loosening the `screw 26, the rod 23carrying the feeder plug v7, may be rotated through any desired arc to'take care ofV any deformities in the:I

plug, or for otherwiseproperly aligning it l with the flow orifice.After the rodhas beenturned through the desired arc it will beymaintained in its adjusted position by settingl up on the screw 26.

The7 cross arm 11 carries at its opposite end a fin r -27 which duringthe reciproca e feeder ip ug 7 travels up and down in a slot 28 providedin the 'guide mem'- ber 29,;` thus maintaining the plug 7 properlyaligned` with the 'Howorifice.'- Thecros's arm 11 ma be turned with thepiston rod 10, as

a furt er means for accuratel adjusting the eederplug in alignment `witthe flow-orioe;l and 'for guiding the feeder plu in this adjustedposition` we have provide means forl adjustingy thegguide member 29.Refer- .ringl particularly to Figure 3, it will be noted y that thelateral'extens1on30'of/thebase of "cylinder f8, islprovided fwith anarcuate slot 31, and that 'a screw 32" passes through thisslotand'screw-threadedly engages the hori zontal portion 33 of the guidemember 29. To accomplish ,this adjustment it is only necessary-to loosenscrew 32 and turn to the desired extent the guide member, the cross arm,the piston rod, and the feeder plug, as a single unit, and then set upon the screw 32. In the foregoing description we have set forth themanner in which the feeder may be suited to various installations byreason of the adjustment permitted by the elongated opening; 13; and wehave also set forth the liner adjustments by which the feeder plug mayalways be accurately aligned with the flow orifice; namely, thelongitudinal adjustment of the rod 23 in the socket 24, the turningadjustment of the rod 23 in the socket 24, and thel turning adjustmentof the cross arm 11. yW'e shall now describe the readily and sensitiveladgth andl the limits o 'the plunger stroke. l

Referring now to Figures 1 and 2, numeral 34 indicates a rotatablecontroller member which ismounted in a bracket 35. .An annovel means fjusting the le `nular shoulder 36 is provided on the coning arm 37 ofthe bracket 35, and a collar 38 is mounted on the controller above thelaterally extending arm 37. Arranged between the shoulder 36 and the arm37, is a ball bearing race 39; and4 arranged between the collar 38 andvthearm 37-is another ball bearing race 40. In this manner thecontrollerI member/34 is not permitted to move longitudinally withrespect to the bracket, but it is permitted to be rotated therein. To

lprovide means for rotating thecontroller member, thelower end thereofis preferably knurled, vasindicated by numeral 41. Y

.The piston rod 10 extends downwardly through the controller member,.and has pinned thereto, within the 'controller memr, a collar 42. Thiscollar isv arranged be tween two nuts, 43 and 44, which are Ascrew-`threadedlymounted in the controller member `and through which the pistonrod 10 freely passes.' lThe nuts 43v and 44are oppositely threaded, and,preferably the upper nut U43 has left-handed threads and the'lower nutright-handed threads, The nuts are held y against rotation by means ofkeysJ (not shown) Acarried by the nuts, and which ,lit ingo the keyway45 provided in the piston ro 10.

As the piston rod 1.0 is reciprocated the` the nuts 43 and.44 will betroller member be turned in one direction Iv the nut 43 will be elevatedto an extent depending upon the extent of rdtation of the controllermember, and the nut 44 will be simultaneously lowered to exactly thesame extent that the upper is elevated. Thus the length of travel of thefeeder plug 7 is increased, by simultaneously raising its upper limit'and lowering its lower limit to the same extent. On the other hand, byturning the controller member in the opposite direction, the nut 43 willbe lowered to an extent depending upon the extent of rotation of thecontroller member, and the nut 44 will be simultaneously raised toexactly the same extent that the upper nut is lowered. Thus the lengthof travel of the feeder plug is reduced, by simultaneously lowering theupper limit and raising the lower limit to the same extent,

By the adjusting means just described the length of travel of the feederplug is varied lby simultaneously varying in opposite directions and tothe same extent its limits of travel. But it is also desirable in someinstances,'to retain unchanged the length of travel of the feeder plug,and at the same i time change lthe elevation at which the feeder plugr'eciprocates. We have devised an extremely simple means for effectingthis adj ustment; such means being described below.

As stated hereinbefore, the controll r member 34/ has no movement oftranslation with respect to the bracket 35.' Accordingly, for-effectinga vertical movement of the controller, we mount the bracket on ascrewthreaded shaft 46. The shaft 46 is mounted for rotation, butagainst longitudinal -movement, in journals 47, 47, preferably carriedby the bracket- 8, and ball-bearing racesf48, 48, are provided above andbelow the lower journal. The shaft 46 is rotated by means of anoperating handle 49 attached to the shaft in any desired manner.

If the shaft 46 is rotated in one direction itl will 'eleva-te thebracket 35, and thus the con- ,troller member and nuts 43 and .44 willbe lifted bodilytoan extent depending on the vation at whiclr the plugreciprocatesfhas been raised.

If the shaft 46 is rotated in the op osite direction the bracket 35 willbe lowere and the ybeen lowered. f

It will be noted that by the rotation of the controller member the nuts43, 44, are simultaneously moved the same distance in oppositedirections, either toward or from each i other, thereby changing thelength of stroke `of thefee'der plug;v whlle by the rotation of thescrew shaft 46 the nuts 43, 44, are simultaneously moved the samedistance in the same direction, either up or down, thereby maintainingthev len h of stroke the same, but altering the vertical position of thepath of the stroke. It is thus seen that the nuts 43, 44, may be movedsimultaneously toward each other, or simultaneously away from eachother, or they ma be moved simultaneously in the same direction, eitherupwardly or downwardly, but it is apparent that whatever the adjustmentmay be, the nuts must be l'adjusted simultaneously, as it is impossiblein the operation of this mechanism to adjust either nut independently.

In accordance with `the well known and when at the lower limit of itsstroke is always within the well 3 and 4, and,'as a matter of fact, thelower end of the plug is practically always within `the well, even atthe upper limit of its stroke.
